PISTON-ROD LU BR'ICATOR.

Specification of Letters Patent.

Patented Dec. 1 1,' 1906.

Application filed September 10, 1906. SeTifl'LNm 3 To all whom it may concern.-

Be it known that I, CHARLns J. Bosn- MEYER, a citizen of the United States, and a resident of J udsonia, in the county of White and State of Arkansas, have invented a new and Improved Piston-Rod Lubricator, of which the following is a specification.

My invention relates to means for the lubrication of piston-rods, especially those of locomotive air-pumps; and its object is to provide simple and eiiective means to prevent dust from settling on piston-rods, to insure the lubrication of the same, and to act as a lockfor the nuts of the stufiing-boxes.

My invention consists of a casing formed of resilient split sleeves held in position by a spring-ring at the outer end of each sleeve and a third ring placed where one of the sleeves slips over the other.

It further consists of spring-held lubricating-pads mounted on one of the sleeves.

In the accompanying drawings, Figure 1 shows the ends of the cylinders of a locomotive air-pump and my improved lubricator within its casing, part of the casing being broken away. Fig. 2 is a view of the same complete. Fig. 3 1s a view of the lubricator on a somewhat larger scale, part of the casing being broken away. Fig. 4 is an end view of a portion of the pad-supporting sleeve.

Similar reference characters refer to like parts throughout the several views.

In the drawings, the steam-cylinder head 1 of a locomotive air-pump and the pump-cylinder-head 2 are shown provided with stuffing-boxes 3, having the usual gland-nuts 4:, which, together with the piston-rod 5, are of any desirable construction. A split sleeve 6, of spring sheet metal, has a rounded upper edge, against which is placed the spring-ring 7. The sleeve is provided with circumferential corrugations 8. A second sleeve 9 has a ring 10 mounted at its lower edge and a circumierential corrugation at its upper edge to engage the corrugations on the sleeve 6. A split ring 11 is placed in one of the corrugations 8 in the sleeve 6 and holds the parts together.

Secured to the inner side of the sleeve 9 are the sockets 12, in which are mounted the springs 13. These springs support the plates 14, which are formed with tongues 15, that engage the fibrous pads 16, which are adapted to retain the oil or other lubricant employed. Aspout 17 is mounted in the sleeve 6 and provided with two cross-bars 18, which valve is held to close the opening in the sleeve by means of the spring 21. The casing thus formed of the two sleeves 6 and 9 is adapted to so firmly engage the adjacent ends of the nuts 4 as to hold them from turning, thus forming a nutlock. The firm engagement also insures tightness, and thus prevents the entrance of dust. The pressure of the pads or lubricators against the piston-rod will depend upon the stiffness of the springs 13. The casing may be lengthened or shortened, as desired.

To mount the casing on a pump, the rings 7, 10, and 11 are removed and the sleeves separated. The rings 7 and 11 are first sprung over the upper nut 1, the ring 11 below the ring 7. Ring 10 is placed on lower nut 4. The upper sleeve is then placed on the upper nut, being held in place by the rings 7 and 11 being sprung onto the sleeve. The lower sleeve 9 is then properly positioned, being held in place by the ring 10. The sleeve 6 is then pulled down over the sleeve 9 and the ring 11 slipped down into the proper corrugation.

The spring-held valve 20 prevents the admission of dust, but can be pushed back by the spout of an oil-can when the pads 16 are to be filled with oil.

Having now explained my improvements, what I claim as my invention, and desire to secure by Letters Patent, is

1. In a lubricator, the combination of a split sleeve of resilient metal having a flanged end, a split spring-ring adjacent to said end, sockets secured to the inner side of said sleeve, springs mounted in said sockets, plates carried at the free ends of the springs,

lubricating-pads carried by said plates, a

second split sleeve of resilient metal having one flanged end and corrugations near the opposite end adapted to slip over the end of the first sleeve, a split spring-ring adjacent to said flanged end, a third split spring-ring 10o adapted to fit around said second sleeve in the corrugations and hold said sleeves in proper position.

2. In a lubricator, the combination of a split metal sleeve, springs secured to the [o5 inner side of the same, lubricating-pads mounted on the free ends of the springs, a second split metal sleeve adapted to fit over one end of the first, an oil-spout mounted in the second sleeve, a spring-held valve mount- 1 re ed in said spout, and spring-rings adapted to hold the parts in proper position.

3. In a lubricator, the combination of a I pair of split metal rings, the end of one fitting 5 into the other, and spring lubricating-pads mounted in one of said sleeves.

4. In a lubricator. the combination of a pair of split metal rings, the end of one fitting into the other, spring-supported lubricatingi pads mounted in one of said sleeves, and an 10 oil-spout mounted in the other sleeve.
